Description

The present invention relates to an in-vehicle antenna device including a camera.

Conventionally, as in Patent Document 1, an in-vehicle antenna device including a camera has been proposed.

Japanese Unexamined Patent Publication No. 2016-116048

However, when the camera is attached to a member different from the antenna base, such as an inner case, it is not easy to assemble. The assembly was performed, for example, as follows. With the camera cable passed through the base opening, cover the antenna base with the inner case so that the camera cable extends out of the inner case from the camera mounting opening. Then, after connecting the camera cable to the camera, the camera cable extending from the base opening is pulled toward the base opening side to fix the camera to the inner case.

Therefore, an object of the present invention is to provide an in-vehicle antenna device including a camera that facilitates assembly.

The in-vehicle antenna device according to the present invention includes an antenna case having an internal accommodation space, an antenna base covered with the antenna case from above to form an accommodation space, and an antenna held by the antenna base and accommodated in the accommodation space. It comprises an element and a camera housed in a containment space, the antenna base has a wall portion extending upward, and the camera is fixed to the wall portion.

The camera is fixed to the antenna base.
At this time, it is not necessary to wire a camera cable between a member different from the antenna base and the antenna base.
Therefore, as compared with the form in which the camera is fixed to a member different from the antenna base, the wiring work of the camera cable can be simplified, and the assembly of the in-vehicle antenna device can be facilitated.

In addition, the camera is attached to the upwardly raised area (wall portion) of the antenna base.
Therefore, the assembly of the in-vehicle antenna device can be facilitated as compared with the form in which the camera is attached to the planar shape portion of the antenna base.

Preferably, it further comprises an inner case that is arranged in the accommodation space and forms an internal space with the antenna base, and the antenna element is arranged in the internal space.

With the antenna base and inner case, the antenna element housed inside can be waterproofed.

Further, preferably, the height of the wall portion decreases in a slope shape in the direction from the camera toward the wall portion.

In a form in which the force applied to the inner pad is not uniform, such as when the upper part of the wall portion has a staircase shape, water easily penetrates into a place where the force applied to the inner pad is weak.
Since the wall portion has a slope shape, the force applied to the inner pad in the direction perpendicular to the surface formed by the inner pad is substantially the same regardless of the inner pad.
Therefore, the waterproof property can be improved as compared with the form in which the upper part of the wall portion does not have a slope shape.

More preferably, it is further provided with an inner case that is arranged in the accommodation space and covers the wall portion from above to form an internal space, and the antenna element is arranged in the internal space.

Further, preferably, an inner case that is arranged in the accommodation space and forms an internal space with the antenna base is further provided, covers the opening of the inner case, and at least a part of a lens that guides external light to the imaging surface of the camera, or The lens cover that protects the lens maintains watertightness with the inner case.

The inner case covers the camera, etc. with the lens or lens cover waterproof.
As a result, the length of the inner case can be increased as compared with the form in which the inner case covers the antenna element or the like without covering the camera.
Therefore, the degree of freedom in arranging the antenna elements arranged inside the inner case can be increased.

As described above, according to the present invention, it is possible to provide an in-vehicle antenna device including a camera that facilitates assembly.

Further, compared with the form in which the first camera cable 19b is pulled toward the lower surface opening 161b after the first connector 18b and the first camera 18a are connected to fix the first camera 18a, the first camera cable 19b is used. The step of pulling to the lower surface opening 161b side can be omitted. Therefore, it is possible to prepare the assembly of the first in-vehicle antenna device 1 with a small number of man-hours.

Further, the first camera 18a can be mounted at a high position. Therefore, as compared with the form in which the first camera 18a is attached to the flat portion of the first resin base 16, the first camera cable 19b can be wired below the first resin base 16 without being significantly bent. Since it is not necessary to bend the first camera cable 19b significantly, it is possible to suppress damage such as disconnection of the first camera cable 19b.

As a result, the third inner case 32 does not cover the third connector 38b and the third camera 38a, but covers the third antenna element 33a and the third antenna substrate 33b, and the third inner case 32 covers the third camera. The length of the third inner case 32 in the x direction can be increased as compared with the form in which the third antenna element 33a, the third antenna substrate 33b, and the third connector 38b are covered without covering the 38a.
Therefore, the degree of freedom in arranging the third antenna element 33a arranged inside the third inner case 32 can be increased.

The third metal base 37 may form a part of the third resin base 36 (a part of the third wall portion 361 or a part of the third flat surface portion 362).
Specifically, it is conceivable that the member corresponding to the third metal base 37 is also made of resin and is integrally formed with the third resin base 36.

Further, the mode in which the lens cover 32b is attached to the third inner case 32 via the third seal member 40a has been described. However, at least a part of the lens of the third camera 38a may be attached to the third inner case 32 via the third seal member 40a.

In the first to third embodiments, the form in which the antenna element is arranged on the front side in the x direction and the camera is arranged on the rear side in the x direction has been described. However, the positional relationship between the antenna element and the camera is not limited to this.
For example, the antenna element may be arranged on the rear side in the x direction, and the camera whose image pickup surface of the image pickup element faces the front of the vehicle may be arranged on the front side in the x direction.
